Many applications that use 110V/230V-ac mains require a ZCD (zero-crossing-detection) circuit for the ac-line voltage, for example, to synchronize the switching of loads. One method of ZCD uses a high ...
Explanation of how a diode divider can tame powerline noise on a zero-crossing detector's input circuit, improving ZCD sensitivity. To properly control ac sources using solid-state devices, you need a ...
